Human activities are fundamentally altering biodiversity. Projections of declines at the global
scale are contrasted by highly variable trends at local scales, suggesting that biodiversity …

The extent to which biodiversity change in local assemblages contributes to global
biodiversity loss is poorly understood. We analyzed 100 time series from biomes across …

Scientists disagree about the nature of biodiversity change. While there is evidence for
widespread declines from population surveys, assemblage surveys reveal a mix of declines …

Abstract Motivation The BioTIME database contains raw data on species identities and
abundances in ecological assemblages through time. These data enable users to calculate …

Over the past 30 years, one of the most rapidly expanding areas in ecology has been the
development of structured population models, where individuals have attributes such as …

Global biodiversity assessments have highlighted land-use change as a key driver of
biodiversity change. However, there is little empirical evidence of how habitat …

Niche differences and average fitness differences jointly determine coexistence. However,
little empirical information about the magnitude of these two mechanisms is available. Using …

A change in a climate variable may alter a species' abundance not only through a direct
effect on that species' vital rates, but also through 'indirect'effects mediated by species …

Many theoretical models of community dynamics predict that species richness (S) and total
abundance (N) are regulated in their temporal fluctuations. We present novel evidence for …

In observational demographic data, the number of measured factors that could potentially
drive demography (such as daily weather records between two censuses) can easily exceed …
